Specification of Letters Patent.

Patented May 4, 1920.

Application filed December 20, 1915. Serial No. 67,844.

To all whom it may concern Be it known that l, THOMAS M. JoLLnY, acitizen of the United States, residing at Des Moines, in the county ofPolk and State of Iowa, have invented certain new and usefulImprovements in Music-Leaf Turners, of which the following is aspecification.

My present invention relates to certain new and useful improvements inmusic leat' turners and analogous devices; and as its primary object, itcontemplates the provision of a device of this character, which includesnovel means to operate the several engaging arms whereby they may beproperly controlled and made to turn the leaves or sheets of music inproper equence and mechanism to cause the releasement or" the engagingarms at the termination of a stroke so that the turned leaves will bethus held in an advantageous position.

Another object of my invention, resides in the provision of improvedmeans which may be so operated as to turn the respective leaves ineither direction so that the operator will have complete controlthereof, at all times during the operation of the device.

A further object oi my invention is to provide novel engaging arms to beassociated with the several sheets to be turned and which areconstructed in a manner whereby they will be automatically disengagedfrom the operating mechanism at the termination of a single stroke.

A still further object of my invention is to provide a device of thetype in question that is extremely simple in construction, strong anddurable, and highly practical from both the standpoint of themanufacturer and the standpoint of the user; and which, it is believed,may be manufactured at a comparatively low cost.

Various other objects and advantages will become apparent during thecontinuance of the following description.

These objects are accomplished by such means as are shown in theirpreferred form in the accompanying drawings, described in the followingspecification and then more specifically pointed out in the appendedclaims.

In' the accompanying drawings wherein like charac ers designate likeparts throughout the several views;

Figure 1 is a view in front elevation illustrating my invention as inits preferred em lodiment, the several engaging arms being shown in anoperative position;

Fig. 2 is a fragmentary view illustrating more clearly the method ofmounting the several engaging arms and the relative position of theoperating mechanism;

Fig. 3 is a view partly in section and partly in side elevation showingthe back or body structure of the device in cross section;

Fig. 4 is a view similar to Fig. 2 showing more clearly the operatingmechanism for the several engaging arms;

Fig. 5 is a view in detail of an improved structure that is designed tosupport one of the operating shafts;

Fig. 6 is a detail view illustrating a member that is designed tocooperate with the several engaging arms and the operating mechanism ofthe device such as will be he..einaiter fully pointed out;

7 is a view showing the relative disposition oi" the engaging arms atthe beginning of the operation of the device.

in reducing" my invention to practice, I first provide a back or bodyportion 10 that may bei'ormed of any suitable or desirable material, andwhich carries suitable casings 11 and 12 respectively to containordinary clock work mechanisms or any other means designed to operatethe several shafts. This back or body portion 10 may be ronstructed in amanner whereby it may be conveniently supported upon a tripod or othersimilar device, such as would retain the same in full view of theoperator, at all times. Although not limiting myself to any specificmeans to support the device, the re spective casings 11 and 12 may beprovided with gudgeons 13 whereby they may be readily connected to asuitable support.

Spaced bearings 14 and 15 respectively mav be arranged on the back orbody member 10, substantially in the manner shown, the bearing 14: beingdesigned to support a depending sleeve 16 in proximity to the easingwhile the other bearing is designed to receive a tubular standard 1'?that is connected in a suitable manner with the casing 12. In order toretain the sleeve 16 and the standard 17 in a secure position at alltimes and to prevent the accidental dislodgment thereof, during theoperation of the device, suitable retaining members, such for instanceas designated by the numeral 18 may be provided which are designed tocon" nect with the body member 10, substantially in the manner shown. Itis pointed out that any number of the bearings 14 and 15 and theretaining members 18 may be provided,

' since this is a mere arbitrary feature and is provided with, first, arigid shaft 2O,

whose hollowed end ..1 receives the reduced portion 22 of the shaft 19and, secondly a tubular operating shaft which incases the shaft 20 inthe manner shown in Fig. 4. It will be noted that the shaft 20, servesin a sense, as a support for the shaft 19, while the shafts 19 and 23are free to move independently of each other, if it is so desired. It iscontemplated that the casing 11 be provided with clock work mechanism toturn the shaft 19 in one directionwhile the other casing carriesmechanisms to actuate the shaft 23 in an opposite direction. Thus itwill be seen that the leaves may be turned in one direction, by theactuation of one shaft, and in the other direction, by the operation ofthe other.

At its lower end, the sleeve 16 is slightly reduced as at 24, the saidreduced portion being screw threaded about its periphery so as toreceive a similarly formed cap 25; the latter in turn carrying a tubularbearing 26 to fit about the shaft 19 such as shown in Figs. 1 and 2, andat the same time serve as a bearing for the several engaging arms, suchas will be presently pointed out. This bearing 26 is also provided witha stepping portion 27, such as shown in Fig. 2, whereby it may be madeto support the several engaging arms. In effect, the elements 16, 24 and25 constitute a tubular shaft reduced intermediate of its ends so as toform a pivot and a bearing shoulder for pivot-ally supporting the arms39.

At its lower end, the shaft 19 is provided with a projecting actuatingarm 28, which, when moved in the arc of a circle, may be made to passthrough a slot 29 of the body member 10. This actuating arm may also beengaged with certain elements of the engaging arms, such as will bepresently pointed out. Adjacent its connection with the shaft 19, thearm 28 is formed into a suitable eye having its upper surface cutslanting at an angle, so as to provide a cam-face as indicated by thenumeral 30 in Fig. 4, which CQDI-fZICQ cooperates with the slantingunder side or cam-face of the supporting member 27 so that the arm 28constitutes a cam-lever having the upper edge of a member 35 as itsfulcrum so that the ends of said arm will be raised and lowered slightlyduring its operation by the shaft 19. The shaft 23 is provided with anactuating arm 31 which may be made to project through a slot 32 of thebody 10, and has the underface of its eye portions cut slanting as at 33so that it will be raised and lowered in the same manner as the arm 28,during its operation by the shaft 23. In this connection it willbenoted'that the stop 27 is spaced from the upper end of the standard 17and the shafts arranged in the said standard, and, owing-to the inclinedor slanting arrangement of the opposing faces of the stop and standardthe space therebetween is con siderably less at the point farthest awayfrom the backing 19 than it is at the point immediately adjacent saidbacking. It will therefore be seen that as the arms 28 and 31 whenextended in normal position through the slots 29 and 32 are arrangedrespectively above and below the plane of the restricted portion of thisspace it will be evident that these arms must move vertically as theyrevolve so as to properly pass through this restricted portion andactuate the leaf turning arms as will be hereinafter more apparent.

A collar 34 is fixed to the rigid shaft 20 adjacent its upper end, suchas shown in Fig. 4, and is provided with a branched guiding member 35,which is inturn connected with the body 10, as at 36 and 37respectively. This branched guiding member 35 is substantially wedgeshaped in cross section and is positioned between the slots 29 and 32 toserve as a guide for the arms 28 and 31 as these arms move in the arc ofa circle across the front face of the backing. Being wedge shaped itwill be evident that the inclined upper and lower faces of this guidemember will permit the necessary vertical movement of said arms, itbeing understood that the arms engage said faces as they revolve withthe shafts 19 and 23.

Eyes 38 are mounted to be movable upon the bearing 26 (see Fig. 2), eachof the said eyes being provided with a projecting stud or arm 39. Thestuds 39 are in turn pivotally connected with the engaging arms 40 as at41, for supporting said engaging arms while leaf springs 42 are employedto force the engaging arms downwardly. The engaging arms 40 may be ofany desired construction; however, in the present embodiment, the sameare provided with vertical intermediate end portions 43 adjacent theirinner ends, whereby they may be made to engage the respective leavesmore effectually, and depending fingers 44 which may be engaged by theactuating arms 28 and 31 at certain times, such as will be hereinaftermore fully pointed out.

Members 45 which have their front faces cut slanting as at 46 may befixed upon the body member 10 in proximity to the arms 40 through theinstrumentality of the studs 47 These members may also be provided withsuitably curved leaf springs 48 secured in place by rivets as at 49,which springs 48 are designed to engage with the arms 40, at certaintimes, to hold the said arms in a proper position whereby the fingersmay be properly engaged by the actuating arms. WVhen the arms areengaged upon the inclined face of one of the members 45 as shown inFigs. 1 and 2 it will be seen that the fingers of the upper arms will beraised slightly higher than the fingers of the lower arm respectively.Therefore when the low ermost arm is engaged by one of the actuatingmembers 28 or 31 and moved across to the opposite side of the backing 10the remaining arms will gravitate downwardly along the inclined face ofthe said member 45 so as to bring the next lowest arm supported thereoninto a position where it will be engaged by one of the actuating memberson its next movement.

With a view of facilitating the operation of the device, I attach acable 50 to the actuating arm of the clock work mechanism in the casing11, while a plunger or rod 51 is con nected with the clock workmechanism in the casing 12. Bell crank levers 52 and 53 respectively arepivotally mounted upon the body member 10 as at 54, one arm thereofbeing connected with the cable 50 and the rod 51, while their other armhas connection with the actuating cables 55 and 56, which are in turnconnected with lugs 57 of suitable finger engaging portions 58. Uponactuation of the finger engaging portion 58 to the right in Fig. 1 theclock work mechanism in the casing 11 will be released so as to causethe actuation of the arm 28 while the other finger engaging portion willrelease the clock work mechanism in the casing 12, such as will causethe operation of the arm 31.

In the operation of my invention, the several arms 40 are first arrangedbetween the several sheets to be turned and then engaged upon theinclined supporting face of one of the members 45 whereby the finger 44of the lower arm will project slightly below the fingers of the otherarms. Now by depressing the finger engaging portion 58 to the right inFig. 1, the clock work mechanism in the casing 11 will be released andwill cause the positive actuation of the shaft 19 and similar movementof the actuating arm 28. Immediately upon movement, the arm 28 will tendto move slightly downwardly, caused by the contact between its slantingface 30 and the slanting face of the stop member 27 so that afterleaving the slot 29, it will move materially below the plane thereofbeing guided in such movement by engagement with the adjacent inclinedface of the branch guiding member 35. As the lower finger 44 is engagedby the actuating arm 28 the leaf turning arm 40 and studs 39 from whichthe finger depends will be moved to the opposite side of the packing soas to properly turn the leaf engaged therewith. IVhen the arm 40 hasreached the end of its stroke, and is engaged with the leaf spring 48 ofthe other or op positely arranged member 45, it will be forced slightlyupwardly as is obvious thereby causing the disengagement of the arm 28and the respective finger 44. At this time the arm 28 will again bebrought in engagement with the guiding member 35 whereby it will bereturned to its normal position within the slot 29.

On the other hand, should the operator desire to turn the leaf in theopposite direction, a finger engaging portion 58 at the left in Fig. 1may be depressed such as will cause the releasement of the clock workmechanism in the casing 12 and the consequent rotation of the shaft 23and the actuating arm 31. This arm will be moved in practically the samemanner as the arm 28 and therefore, it is not believed that furtherdescription will be required.

From the foregoing, it will be seen that the device may be employed toeffectually turn the sheets in both directions and that simply one sheetmay be turned and reversed in accordance with the desire of theoperator. In view of the fact that the advantages and novel features ofthe invention will be readily apparent from the foregoing, furtherdetail description thereof is deemed unnecessary.

In reducing my invention to practice, I find that the form referred toherein as the most practical and preferred embodiment is the mostellicient, but realizing that certain conditions will necessarily varyin concurrence with the adoption of my device, I desire to emphasize thefact that various minor changes in details of construction and theproportion of parts may be resorted to when required, withoutsacrificing any of the advantages of my invention as defined in theappended claims.
